This is a very high yield episode to help you review for the anesthesia board exam. I cover the board key word section entitled gas laws which includes a focus on volatile anesthetics, their properties, and how they act on, and in, the human body.
Topics covered will include:
Vaporizer Types and safety features
If you accidentally filled your sevo vaporizer with iso, what would happen? Why?
Why does desflurane have its own special type of vaporizer?
What happens when you use a variable bypass vaporizer at altitude?
Why would Des be different at altitude?
Uptake and elimination
Most important concept?
What effect does a R→L intracardiac shunt have on the rate of inhaled induction of anesthesia?
Why more effect on poorly soluble agents?
Additional intracardiac shunt effects (19:50)
What is the blood-gas solubility coefficient?
Effects of ventilation and circulation
What effect does increased alveolar ventilation have on inhaled induction?
More affect on soluble or insoluble?
How is solubility of gas affected by endobronchial intubation?
How does cardiac output affect onset of inhaled induction?
Why inhaled induction so fast in infants?
